Aniakchak reported activity





Event Name : Aniakchak 2016 regional earthquake

Start:April 2, 2016 Observed

Eruption Type:Not an eruption.

Description: From Cameron and others, 2020: "Volcanic activity did not occur at Aniakchak volcano (an informal designation used by AVO to refer to the volcano that comprises Aniakchak Crater and the volcanic features in its vicinity) in 2016, but a magnitude 6.2 earthquake occurred 20 km east-southeast of Aniakchak caldera on April 2. This earthquake was followed by an energetic aftershock sequence, and most earthquakes were located in the upper 20 km of the crust. The earthquake and associated aftershock sequence were thrust events and nonvolcanic, although AVO seismologists closely monitored the activity in case a volcanic event was triggered by the regional earthquake sequence. The Aviation Color Code and Volcano Alert Level remained at GREEN and NORMAL, respectively."
